The contact rod is driven through a moving contact by the vacuum arc-extinguishing chamber in the utility model to shift the shifting fork of the vacuum arc-extinguishing chamber to realize the switching-on and switching-off actions of the vacuum arc-extinguishing chamber, the arc contact plate is turned along with the moving contact to realize the switching-on and switching-off actions with the arc contact, the vacuum arc-extinguishing chamber is separated from a main through-current loop when a main switch is switched on to normally switch on current, does not switch on the current and can effectively avoid damage caused by switching on the current to the vacuum arc-extinguishing chamber for a long time, special processing is carried out for both the surface of the vacuum arc-extinguishing chamber and the outside of a driving mechanism, and the utility model is more beneficial to being used in outdoor environments, so that the utility model has simple and compact structure, steady and reliable action, good matching time sequence and long service life.
Description
Technical field
The utility model relates to a kind of structure that is applied to the isolating switch in the extra-high voltage electric power system, a kind of specifically extra-high-voltage isolated switch folding big-parameter bus switching current device.
Background technology
UHV transmission has the inherent characteristic that big capacity, remote, low-loss, province take up an area of, and is the power transmission mode that meets China's fundamental realities of the country.The employing of UHV transmission technology realizes wider most optimum distribution of resources, promotes the efficient development and utilization of China's energy, promotes the sustainable development of economy and society.Development along with China's extra-high voltage grid, the ability and the scale of China's network optimization resource distribution will significantly improve, will greatly promote the effective exploitation and efficient utilization of domestic energy resources, further improve power network safety operation level and anti-accident ability, the demand of national economy and social development to electric power satisfied in the cooperation of strong simultaneously promotion international energy.High-voltage alternating current isolating switch is one of capital equipment in the high-tension power transmission and transformation equipment, is maximum a kind of of expense, normally 2～4 of circuit breaker times, so in electric power system, occupy an important position.Because use amount is big, functional reliability is required than higher, to electric substation,
Power plantThe influence of design, foundation and safe operation all bigger.Present outdoor extra-high-voltage alternating current isolating switch structure especially can't satisfy the parameter request of folding bus switching current 6kV, 6300A owing to the deficiency that exists in the design, is restricting the paces that China's extra high voltage line is built.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of extra-high-voltage isolated switch folding big-parameter bus switching current device, specifically be applied to the three-post horizontally turning type extra-high voltage series compensation parallel-connection isolating switch, have simple and compact for structure, stable action is reliable, matching timing is good, the characteristics of long service life.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
Include auxiliary contact, touch rod, arc control device support, shift fork, vacuum interrupter, insulating rod, arcing contact, support and arc touch panel, auxiliary contact is arranged on the stationary contact headstock, touching rod is arranged on the moving contact, the end that touches rod is provided with the arc touch panel, vacuum interrupter is arranged on the stationary contact headstock by the arc control device support, mechanism's main shaft of vacuum interrupter is provided with shift fork, and support is fixed on the stationary contact headstock by insulating rod, and support is provided with arcing contact.
Described centre and shift fork contact position position of touching rod is provided with roller.
Described roller and touch and be provided with insulating case between the rod.
Described vacuum extinction chamber surface adopts epoxy casting.
The transmission mechanism outer setting of described vacuum interrupter has totally enclosed stainless steel casing.
When the three-post horizontally turning type extra-high voltage series compensation parallel-connection isolating switch closes a floodgate, moving contact rotates in horizontal plane, the arc touch panel is contacted with arcing contact, then touching rod stirs shift fork vacuum interrupter is closed a floodgate, touching rod then contacts with auxiliary contact, last moving contact upset and fixed contact positive engagement make the arc touch panel separate with arcing contact simultaneously; During separating brake, moving contact upset breaks away from fixed contact, and the arc touch panel contact with arcing contact, follows moving contact and rotates in horizontal plane, touches excellently to separate with auxiliary contact, touches rod and stirs shift fork and make the vacuum interrupter separating brake, and the arc touch panel separates with arcing contact then.
In sum, vacuum interrupter touches rod by the moving contact drive and stirs the vacuum interrupter shift fork to realize the divide-shut brake action of vacuum interrupter in the utility model, the arc touch panel overturns with moving contact, with the divide-shut brake action of realization with arcing contact, and vacuum interrupter is in the main switch cutter normal main through-flow loop that breaks away from when through-flow of closing a floodgate, not through-flow, can effectively avoid the long-term through-flow damage that causes of vacuum interrupter.All done special processing on the surface of vacuum interrupter and the outside of transmission mechanism, helped it more and be used for outdoor environment, therefore simple and compact for structure, stable action is reliable, matching timing is good, long service life.
